[Beowulf] HPC and Free Air Cooling

Hi everybody,
We are about to deploy a Infiniband Cluster, using Free Air Cooling
combined with HVAC equipment to deal with the Data Center cooling, and
we try to contact people having similar experiences.
We particularly would like to have your opinion on:
- Relative Humidity control ranges (10 - 80% rather than 40 - 60%)
- Impact on hardware degradation
- Effects of air contaminants combined with high relative humidities
I'll be glad to hear from you and your experiences on the concern.
Best regards
